Iguin is the Brimmed Hat Witch who sold a book of forbidden magic to Coco. His motivation is somewhat unknown, but it has something to do with Coco. He appears to be incredibly powerful, possessing magic that is beyond the scope of normal witches. Iguin also has incredible agility, being able to jump while casting magic. He rarely appears except to interfere with Coco from the sidelines.

In a world where everyone takes wonders like magic spells and dragons for granted, Coco is a girl with a simple dream: she wants to be a witch. But everybody knows magicians are born, not made, and Coco was not born with a gift for magic. Resigned to her un-magical life, Coco is about to give up on her dream to become a witch … until the day she meets Qifrey, a mysterious, traveling magician. After secretly seeing Qifrey perform magic in a way she’s never seen before, Coco soon learns what everybody “knows” might not be the truth, and discovers that her magical dream may not be as far away as it may seem...
